corpora flan of Virginia Application August 4, 19:2, Serial No. 021,438 Renewed May 28, 1937 3 Claims. 101-350) This invention relates to ink fountains for printing presses and the like and particularly for presses printing in different colors.

The principal objects of the invention are to provide the fountain of the inking device in a plurality of units, individually removable; to provide an ink fountain of a length less than the full width of the paper to be printed, and to provide a fountain having separately removable containers for inks of different colors.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which I Fig. 1 is an end view of a part of a printing press showing a preferred embodiment of this invention, the fountain being shown in section;

Fig. 2 is a plan of a part of the ink fountain;

Fig. 3 is a side elevation; I

Fig. 4 is a sectional view of a part of th fountain showing the adjusting device.

When different colored inks are used in the same inking system, it has been customary heretofore to have a single fountain with partitions in it separating it into compartments for the different color inks. This involves some clifllculty owing to leakage through the partitions and especially to the fact that it is difficult to clean one of the compartments when it has to be emptied and a different colored ink put in. it. This invention is designed to eliminate these difiiculties and to avoid the delay and difficulty of the cleaning of the fountains.

The invention is shown as applied to an inking mechanism for a newspaper or the like having a fountain for each page width of the press, the fountain being shown as of the overshot type, although the invention is not limited to that type of fountain. Only the plate cylinder 2 of the printing couple is shown and it is illustrated as supplied with ink through a system of the ordinary type, which involves form rolls 3, ink drum 4, distributor 5, transfer roller 6, pick-up roller I and spray catcher 8. The fountain roll 9 runs very close to the pick-up roller 1 but does not touch it. These inking rollers are arranged as is usual in this art.

The combined fountain is made up of fountain roll sections 9, each one of approximately one page width, that is, sufficiently wide to ink a single page. Each fountain roll is rotatably supported in a small fountain bowl i0. Each one of-these'bowls constitutes a section of the main fountain in the same way that the short fountain roll does' of the main fountain roll.

Each fountain roll is driven through a gear ll secured to the end which projects through the fountain bowl. It meshes with a gear i2, carried on the shaft i3 whichextends across the width of the press. The shaft II is driven from a source of power through bevel gears l4 and ii. of course, there is one gear [2 for each movable fountain which cooperates with its corresponding gear ii carried on the. end of that particular fountain roll.

A brace it provides means for mounting each removable fountain bowl I0 which rests on a machined surface on its upper side. This machined surface cooperates with feet ii on the several fountain bowls and the latter carry a T-slot construction fitting over T-bars I8. These T-bars are yieldingly pressed upwardly by springs iii to provide a clearance so that the fountain bowl ll may be slipped on and held in position. Adjusting lugs 2i are provided which threadedly carry adjusting screws 23. These screws 23 bear against bars 29 which may be considered as integral with the brace l6 and extend between feet I'I. They are used for adjusting the fountain roll to the desired distance from the pick-up roll I. Each individual fountain bowl of course is adjusted in a way to adjust the position of its fountain roll.

Each fountain bowl is fixed in adjusted position by a hinged bolt 28 secured to bar 29 and thumb nut 22 so that good inking can be obtained. Each fountain bowl IQ is securely clamped by lock bolts 2. to the brace It by the T-bars i8 against the underslung ledges of the fountain bowl.

In each fountain bowl is a fountain back 24 secured to provide a rigid mounting for the blade 25 by a clamping strip 26. The usual fountain blade adjusting screws 21 are provided and regulated in the usual manner.

The adjustments have been described and the method of fastening the parts in position. When it is desired to clean one of the fountain bowls Iii, the bolts 20 are loosened, wing nuts 22 are loosened and bolts 28 swing down, permitting the entire bowl with its contents to be lifted free of the press without disturbing the other fountain bowls. The ink may be emptied and the fountain thoroughly cleaned in an efficient and easy manner and returned to position with equal facility.

Although I have illustrated and described only one form of the invention I am aware of the fact that modifications can be made therein by any person skilled in the art without departing .from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited in this respect otherwise than as set forth in the claims, but what I claim is:

1. In a printing press, the combination with a plate cylinder and a series of rolls for transfers-ins ink thereto. of a plurality of fountain bowls arranged end to end, a fountain roll in each bowl for supplying ink to the ink rolls, said fountain roll being less than full page width of the press, and quickly detachable means projecting to an accessible point in front of the bowl whereby each fountain bowl is independently detachable and removable.

2. In an inking device, the combination of a plurality of fountain bowls, each one of a width sumcient to supply ink for a single page of the printed product, a fountain roll therein of substantially the same width, a brace running under the several bowls, open slotted lull curied by said bowls, jointed adjusting screws extending through the lugs and capable of beinx detached from them readily, and a bar integral with the brace against which said screws bear whereby the bowl may be individually adjusted.

3. In an inking' device, the combination of a plurality of separate ink bowls, a plurality of T-bars extending under said bowls, said bowls having feet in which T-slots are provided for receiving the T-bars, means for pressing said T- bars upwardly and yieldingly, and means for clamping the T-bars down in position to hold the HENRY A.
